ah. Using the piston ring installing tool, slide
power piston plug (96) over piston (99) until the ad-
vance adjusting screw (112) enters threaded hole in
ai. Insert screwdriver into advance adjusting
SC reW and turn out screw until approximately one
half inch protrudes from plug. Do not turn pIug on
piston as piston ring damage may result.
aj. Slide assembled piston and plug into advance
bore at C side of advance housing and thread plug
until the cam pin bore is aligned with pin bore of
ak. Install advance pin (102).
al . Place advance spring (108) into piston cavity
and thread the spring side piston hole plug (111) into
am. Tighten both plugs and install adjusting screw
nut (114) and seal (113).
an. Turn the pump back to its original position (top
upward) in the vise.
ao. Install the metering valve (93) and shims (95)
into its bore.
Depress and rotate the valve several
times to insure freedom of movement. If valve
sticks, lap it in carefully with clean oil. Never sand
or polish off the special surface treatment provided.
ap. Pull back on the governor linkage hook (45),
stretching the spring just enough to connect the hook
correctly to the fork on the governor arm (86).
Position the opposite end over the pin on the metering
valve arm (91 ). Check all of the governor parts again
for freedom of movement.
aq. With end plate removed (59), assemble the
speed droop control rod assembly (79) through
threaded hole from inside of pump housing.
ar. Slide speed droop guide (75) with O-ring
seal (77) assembled over end of rod (79) and
thread into rear of housing.
Do not overtighten;
allow O. 010 clearance between guide (75) and
pump housing face,
The apparent looseness in the governor
parts is normal.
Lost motion is im-
mediately taken up as soon as the pump
aw. Assemble the throttle shaft assembly (26) and
lever assembly (32) partially through its bore in the
housing. Slide the spacer bushing (38) and throttle
shaft lever (40) over the throttle shaft so that the
projection on the throttle shaft lever bore engages
the keyway on the shaft.
Position the forked end of
the throttle lever so that it straddles the guide stud.
Apply a light coat of grease to the throttle and shut-
off shaft seals (35, 3 6). Assemble the shut-off
shaft assembly (24) from the opposite side with a
slight rotary motion.
So as not to damage the seal,
firmly seat the two levers. Locate and seat the shut-
off cam (25).
ax. With the throttle lever in wide open position,
check the clearance between the rear of the shut-off
shaft (B) and the vertical tab (A) on the linkage hook.
This clearance should be O. 250 inch.
Adjustment of this clearance in the pump
is made by changing the effective length
of linkage hook.
ay. With adjusting screw (C) tight, apply a slight
pressure to tab (A). At the same time rotate pump
one or two complete revolutions to assure that link-
age is in full forward position. Loosen adjusting
screw (C) and slide linkage to maximum open length.
Insert linkage gauge between vertical tab (A) and
shut-off shaft (B) and slide linkage hook together
from rear until face of tab is flush against gauge.
Tighten adjusting screw (C). Check adjustment and
reset if required.
az. Check all governor parts for freedom of move-
ment. Assemble a new seal (6) to cover (4), and in-
stall cover on pump, tightening the three retaining
screws (1) securely.
14-46. Solenoid Inspection and Repair.
as. Insert clip (78) into hole at end of rod (79).
at. Assemble seal (74) to groove at end of guide
(75)and adjust speed droop cap assembly (73) over
au. Install end plate making certain locating pin
enters slot in transfer pump liner. Assemble flat
(61) and lock (62) washers four end plate screws (60)
and tighten to 35 inch-pounds.
av. Thread five full turns of spring (80) onto speed
droop rod assembly (79). Slip free end of spring
(80) o er formed ends of governor arm (86) with the
bent-in ends of the spring between the two tabs.
a. Crank engine and check for 24 Vdc across sol-
en~d leads on top of injection pump.
b. If voltage exists, loosen an injector coupling
an~check for full line of fuel. If fuel is not available,
solenoid has failed.
c. Remove the cover contact nuts (7, 8) and
was%ers (9, 10) and work the solenoid assembly out
of the cover.
Remove the shut-off spring (13) guide
(14), and arm (15).
d. Examine the solenoid visually for cracks and
sw~ling in the encapsulating materiaI and looseness
